Over the last years, the use of raw materials derived from End of Life Tires (ELTs) has found several applications, which have al-lowed a gradual waste reduction through its reuse in different production sectors. In this context, the present paper deals with the mechanical characterization of reinforced concrete with steel fibres recycled from ELTs. Concrete is generally considered a brittle material with a low tensile strength and a slight ultimate strain. Steel fibres are often used as discontinuous reinforcement in the concrete matrix to bridge the cracks that develop when a load is applied, improving its toughness and post-cracking behaviour. The discussed experimental work is part of a wider scientific investigation concerning the introduction of recycled steel fibres in civil en-gineering production sectors. The main founds on the mechanical behaviour of the proposed concrete, comparing the results with the corresponding ordinary concrete will be discussed.

Abstract
Over the last years, the use of raw materials derived from End of Life Tires (ELTs) has found several applications, which have al-lowed a gradual waste reduction through its reuse in different production sectors. In this context, the present paper deals with the mechanical characterization of reinforced concrete with steel fibres recycled from ELTs. Concrete is generally considered a brittle material with a low tensile strength and a slight ultimate strain. Steel fibres are often used as discontinuous reinforcement in the concrete matrix to bridge the cracks that develop when a load is applied, improving its toughness and post-cracking behaviour. The discussed experimental work is part of a wider scientific investigation concerning the introduction of recycled steel fibres in civil en-gineering production sectors. The main founds on the mechanical behaviour of the proposed concrete, comparing the results with the corresponding ordinary concrete will be discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
